Problems with SDL+XFree4

Iuri_Fiedoruk · December 14, 2001, 8:41am

Hi, I used SDL for a long time on redhat 6.2 / xfree 3.3.6, but since I
upgrated to redhat 7.2 / xfree 4.1,
SDL have some problems that I’ll try to explain, so maybe someone can
help me.
First my XF86Config:

File generated by XConfigurator.

**********************************************************************

Refer to the XF86Config(4/5) man page for details about the format of

this file.

**********************************************************************

Files section. This allows default font and rgb paths to be set

**********************************************************************

Section “Files”

The location of the RGB database. Note, this is the name of the

file minus the extension (like “.txt” or “.db”). There is normally

no need to change the default.

RgbPath    "/usr/X11R6/lib/X11/rgb"

Multiple FontPath entries are allowed (they are concatenated together)

By default, Red Hat 6.0 and later now use a font server independent of

the X server to render fonts.

FontPath   "unix/:7100"
FontPath   "unix/:7101"

EndSection

**********************************************************************

Server flags section.

**********************************************************************

Section “ServerFlags”

# Uncomment this to cause a core dump at the spot where a signal is
# received.  This may leave the console in an unusable state, but may
# provide a better stack trace in the core dump to aid in debugging
#NoTrapSignals

# Uncomment this to disable the <Crtl><Alt><BS> server abort sequence
# This allows clients to receive this key event.
#DontZap

# Uncomment this to disable the <Crtl><Alt><KP_+>/<KP_-> mode switching

Monitor section

**********************************************************************

Any number of monitor sections may be present

Section “Monitor”

Identifier  "My Monitor"
VendorName  "Unknown"
ModelName   "Unknown"

HorizSync is in kHz unless units are specified.

HorizSync may be a comma separated list of discrete values, or a

comma separated list of ranges of values.

NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR’S

USER MANUAL FOR THE CORRECT NUMBERS.

HorizSync   31.5 - 48.5

VertRefresh is in Hz unless units are specified.

VertRefresh may be a comma separated list of discrete values, or a

comma separated list of ranges of values.

NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR’S

USER MANUAL FOR THE CORRECT NUMBERS.

VertRefresh 50-70

Modes can be specified in two formats. A compact one-line format, or

a multi-line format.

These two are equivalent

ModeLine “1024x768i” 45 1024 1048 1208 1264 768 776 784 817 Interlace

Mode “1024x768i”

DotClock 45

HTimings 1024 1048 1208 1264

VTimings 768 776 784 817

Flags “Interlace”

EndMode

This is a set of standard mode timings. Modes that are out of monitor spec

are automatically deleted by the server (provided the HorizSync and

VertRefresh lines are correct), so there’s no immediate need to

delete mode timings (unless particular mode timings don’t work on your

monitor). With these modes, the best standard mode that your monitor

and video card can support for a given resolution is automatically

used.

(sorry for the long email, but it’s good to give deatils of the problem)
As you can see, my video board is a Trident 3DImage 975, and it works
well, better than I tought it would.
One of the first problems, is that when I remove focus form a SDL
program window, and then return the focus to it,
the external border of my monitor, that normally are black, becomes
colored, normally pink,
so if I move the SDL program window out of the screen, my linux freezes
(completaly, no kernel response).
I tested this several times, and happens every time. Note that I didn’t
had this problem with XFree 3.3.
Another problem are video players… when I return from full screen on a
SDL video program… freeze!
For example, if I right click on noatun when it is playing a video, and
then right click again or press
esc to return to window mode, my machine freezes.
So, my question is simple, there is a fix for it, or should I think in
returning to xfree 3.3 and loose the benefits of
xfree4, and is this a SDL or xfree problem?

Thanks you in advance.

[…XF86Config…]

I didn’t notice anything dangerous in there - although I don’t know that
card and driver. Maybe it’s not detecting VRAM size properly or
something? (That is, verify that X detects the amount you actually have.)

That would make most people worried…

Oops. This definitely sounds like a driver bug. No application should be
able to make X do that - especially without root privileges.

I tested this several times, and happens every time. Note that I didn’t
had this problem with XFree 3.3.

Although it doesn’t happen that often, if you could try 3.3 again, you’d
be sure that the card isn’t broken…

Well, it might be that SDL is good at triggering it, but it seems like an
XFree problem to me.

Try to find all ChangeLogs, BUGS and other docs related to that card -
there might be some hints. Certain features and modes of some cards
aren’t supported, and it happens that you get a hard crash instead of a
warning if you ignore those limitations…

Sounds like a driver issue, honestly. I would check for patches to Xfree4
before going back to 3.3. I would also check whether non-SDL programs
do the same thing.

I think so. I made some tests and found a solution, don’t know why, but
using 24 bits of
color deep fixes the problem (I was using 16 because it is - in theory -
faster).

He hehhe, true. Some people is afraid of 24 too, because in Brazil there
is a “animal game”,
where each animal have a nunber and 24 is deer with means almost the
same as pinky-boy,
and my solution was using 24 bits of color… isn’t those conincidenes
frigtening?

sorry for my poor english, I even had to get a dictionary to help me
remeber deer word.
